DETAILED DESCRIPTION

[0043] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0044] It should be noted that in the description of the present disclosure, unless otherwise specified, the meaning of "a plurality of" is greater than or equal to two; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like are for the purpose of facilitating the description of the present disclosure and simplifying the description, and are not intended to indicate or imply that a referred device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present disclosure. When the absolute position of the described object is changed, the relative positional relationship can also be changed accordingly.

[0045] Please refer to Fig. 1, which is a top view structural schematic diagram of a cleaning host provided by the present application. It can be understood that the F direction, B direction, L direction and R direction marked in Fig. 1 respectively indicate the front direction, back direction, left direction and right direction of the cleaning host 1 provided by the present application. It should be noted that in the description of the present application, the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", "inner", "outer" and the like are for the purpose of facilitating the description of the present disclosure and simplifying the description, and are not intended to indicate or imply that a referred device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present disclosure. When the absolute position of the described object is changed, the relative positional relationship can also be changed accordingly.

[0046] It can be understood that the cleaning host 1 provided by the present application can be applied to mobile cleaning equipment such as a sweeping robot, a mopping robot, a sweeping and mopping integrated robot, etc., and is arranged to be capable of cleaning the environment to be cleaned during movement. The existing cleaning host 1 usually arranges a rolling brush assembly 31, a fan assembly 33 and a wiping and mopping assembly 34, etc. inside the machine body 10, and realizes the cleaning of the environment to be cleaned through brushing, suction and wiping and mopping. However, in the environment to be cleaned, there are large-volume garbage or obstacles, and the traditional cleaning method is difficult to remove large-volume garbage and remove obstacles. Secondly, the cleaning method of the existing cleaning host 1 is difficult to realize the cleaning of corner positions, narrow gaps, high positions, furniture bottom surfaces, wall surfaces and other positions, and there is a certain limitation in the use process. In view of this technical problem, Korean invention patent KR1020240133919A provides a self-moving cleaning equipment with a mechanical arm, which realizes the environmental cleaning of the dead angle of the traditional cleaning host, the removal of large-volume garbage and the removal of obstacles by arranging a mechanical arm including a plurality of driving shafts on the cleaning host, and a mechanical claw for clamping and moving garbage, obstacles and other objects at the end of the mechanical arm away from the machine body, thereby improving the working range of the traditional cleaning host.

[0047] However, in the above-mentioned self-moving cleaning equipment, the mechanical arm is fixed above the machine body of the cleaning host, and the addition of the mechanical arm significantly increases the volume, height and weight of the cleaning host, making it difficult to store the cleaning host and difficult to enter the low bed, the bottom of the cabinet, and clean the environment such as the floor under the bed, thereby seriously affecting the use range of the cleaning equipment. In view of the above technical problem, CN219294021U provides a self-moving cleaning equipment which can fold and store the mechanical arm into the machine body.

[0048] The above-mentioned self-moving cleaning equipment integrates the mechanical arm inside the cleaning host, and the arrangement space of other components inside the cleaning host is occupied to a certain extent, especially the mainboard of the cleaning host. At the same time, due to the addition of the mechanical arm, more elements are integrated on the mainboard of the cleaning host, and accordingly the area of the mainboard is larger than that of the mainboard of the cleaning equipment without the mechanical arm. The mainboard of the existing cleaning host integrating the mechanical arm is usually arranged as a double-layer mainboard of upper and lower mainboards, thereby meeting the demand of arranging the mainboard in a smaller space. However, the double-layer mainboard will inevitably increase the height of the host, thereby affecting the use range of the cleaning host.

[0049] To address the aforementioned technical problems, this invention provides a cleaning host 1. Please refer again to Figure 1, and also to Figures 2, 3, and 4. Figure 2 is a schematic diagram of the internal structure of the cleaning host shown in Figure 1; Figure 3 is a bottom view of the cleaning host shown in Figure 1; and Figure 4 is a schematic diagram of the cleaning host shown in Figure 1 with its cover in a disassembled state. The cleaning host 1 includes a body 10, a control unit 20, a storage compartment 40, a cleaning unit 30, and a robotic arm. The control unit 20, storage compartment 40, and cleaning unit 30 are disposed inside the body 10. The control unit 20 includes a battery pack 21 and a single-layer motherboard 22 disposed above the battery pack 21, with a portion of the single-layer motherboard 22 extending into the storage compartment 40. The robotic arm is configured to be foldable and stored in the storage compartment 40. The top of the body 10 has an opening 101 for the robotic arm to extend out of the body 10 after unfolding, and the robotic arm is configured not to contact the single-layer motherboard 22 during unfolding.

[0050] In some optional embodiments, the body 10 comprises a top cover, a chassis, side walls, and partitions. The top cover, chassis, side walls, and partitions constitute the body 10, and the partitions divide the internal space of the body 10 into multiple sub-cavities. A cleaning unit 30, a storage compartment 40, and a control unit 20 are respectively disposed in each sub-cavity. In some optional embodiments, the control unit 20, the storage compartment 40, and the cleaning unit 30 are arranged sequentially from front to back inside the body 10.

[0051] It is particularly important to emphasize that the aforementioned sub-cavities can be independent of each other or interconnected. The aforementioned top cover, chassis, side walls, and partitions can each be a separate component or a combination of multiple parts. In some optional embodiments, the sub-cavities may also include, but are not limited to, those for housing drive wheels or charging units.

[0052] Understandably, the battery pack 21 is configured to power the various components of the cleaning unit 1. These components include, but are not limited to, the motor 301 for driving the wheels, the main board 22, the fan, the motor 301 for rotating the roller brush and the cloth 342, and the motor 301 for extending and retracting the robotic arm.

[0053] The single-layer motherboard 22 extending into the storage compartment 40 can be understood as follows: the motherboard 22 is configured as a single-layer motherboard, with part of it positioned above the control compartment and battery pack 21, and the other part extending from the rear of the control compartment into the storage compartment 40. This ensures that the motherboard 22 has a large installation area for integrating components, achieving the integration of control components without the need for a double-layer board.

[0054] It should be noted that the cleaning unit 30 being disposed on the body 10 can be understood as at least partially disposed on the body 10, with another part of the cleaning unit 30 extending outside the body 10. For example, referring to Figure 2, the motor of the roller brush assembly 31 of the cleaning unit 30 and the first drive mechanism 341 and the second drive mechanism 343 of the mopping assembly 34 are disposed on the body 10; the roller brush of the roller brush assembly 31 and the mop 342 of the mopping assembly 34 extend from below the body 10 to sweep the body 10, thereby sweeping and mopping the environment to be cleaned below the body 10.

[0055] It is understood that the cleaning host 1 provided by the present invention has a robotic arm that can extend out of the body 10 to grasp and move items such as garbage and obstacles, or to clean the bottom of cabinets, walls, and other surfaces. The robotic arm is designed to be foldable and stored in the storage compartment 40, thus giving the cleaning host 1 provided by the present invention a high degree of integration, small size, low height, and easy storage. At the same time, there is no interference between the robotic arm and the single-layer mainboard 22 set in the storage compartment 40, and the robotic arm does not contact the single-layer mainboard 22 during the unfolding process. Preferably, the cleaning host includes a cover 11 set in the opening 101, and the cover 11 is detachably set from the body 10.

[0056] Please refer again to Figures 1 and 2, and also to Figures 5, 6, 7, and 8. Figure 5 is a cross-sectional view of the cleaning unit shown in Figure 1 along line AA; Figure 6 is a cross-sectional view of the cleaning unit shown in Figure 1 along line BB; Figure 7 is an internal structural diagram of the second type of cleaning unit provided by the present invention; Figure 8 is an internal structural diagram of the third type of cleaning unit provided by the present invention. In some preferred embodiments, the control unit 20 further includes one or more heat sinks 23 for dissipating heat from the control unit 20; wherein, the heat sinks 23 are disposed on at least one side of the left and right sides of the battery pack 21 and / or at least one side of the left and right sides in front of the single-layer motherboard 22.

[0057] Understandably, the addition of the robotic arm significantly increases the energy consumption of the cleaning unit 1. To ensure the working time of the cleaning unit 1 on a single charge, a larger capacity battery pack 21 needs to be installed in the control unit 20. This results in the battery pack 21 of the cleaning unit 1, which integrates the robotic arm, generating more heat during operation. Furthermore, the internal structure of the cleaning unit 1 with the integrated robotic arm is more compact, making heat dissipation even more difficult. Heat accumulation in the control unit 20 can cause overheating of the motherboard 22 and the battery pack 21 of the cleaning unit 1. Overheating of the motherboard 22 can damage control components, affecting the operation of the cleaning unit 1, while overheating of the battery pack 21 can easily cause safety hazards such as fire and explosion.

[0058] Based on the aforementioned technical problems, this embodiment adds a heat sink 23 to the control unit 20 of the cleaning host 1 to dissipate heat from the battery pack 21 and the single-layer motherboard 22 of the control unit 20. It can be understood that the heat sink 23 in this embodiment is configured as a wind-cooled heat dissipation structure, achieving cooling of the control unit 20 by blowing air onto other components of the control unit 20.

[0059] In some embodiments, the cleaning host 1 is provided with an observation device at the front. The observation device is configured to observe the cleaning environment of the cleaning host 1 and acquire image information of the cleaning environment or the position information of surrounding objects. The heat dissipation device 23 is provided on at least one of the left and right sides of the observation device and is configured to blow gas to the control unit 20 located behind it to cool the control unit 20.

[0060] The cleaning host 1 shown in Figures 2, 5, and 6 includes two heat sinks 23, which are respectively located on the left and right sides of the battery pack 21. The cleaning host 1 shown in Figure 7 includes one heat sink 23, which is located on the right side in front of the single-layer motherboard 22. The cleaning host 1 shown in Figure 8 includes four heat sinks 23, which are respectively located on the left and right sides in front of the single-layer motherboard 22 and on the left and right sides of the battery pack 21.

[0061] It is understood that the heat dissipation component 23 in this embodiment may include one, two, three, or four. The heat dissipation component 23 may be disposed on at least one of the left and right sides of the battery pack 21, or on at least one of the left and right sides in front of the single-layer motherboard 22. In some optional embodiments, the cleaning host 1 may also include a side brush assembly 50, which is disposed on one of the left and right sides of the battery pack 21.

[0062] Please refer again to Figures 5, 6, and 7. In some preferred embodiments, the cleaning host 1 includes a heat sink 23 for blowing air onto the battery pack 21 and the single-layer motherboard 22; in some preferred embodiments, the cleaning host 1 includes two heat sinks 23, one for blowing air onto the battery pack 21 and the other for blowing air onto the single-layer motherboard 22.

[0063] It is understood that in the above embodiment, the cleaning host 1 may include a heat sink 23, which blows air onto both the battery pack 21 and the single-layer motherboard 22 to provide air cooling for both. The heat sink 23 may be located on one side of the battery pack 21, or it may be located on one side of the front of the single-layer motherboard 22.

[0064] In the above embodiment, the cleaning host 1 may include two heat sinks 23. One heat sink 23 blows air onto the battery pack 21, and the other heat sink 23 blows air onto the single-layer motherboard 22. The two heat sinks 23 may be arranged opposite each other on the left and right sides of the battery pack 21; or they may be arranged opposite each other on the left and right sides in front of the single-layer motherboard 22; or one heat sink 23 may be arranged on one of the left and right sides of the battery pack 21, and the other heat sink 23 may be arranged on one of the left and right sides in front of the single-layer motherboard 22.

[0065] Please refer again to Figures 2, 7, and 8. In some preferred embodiments, a button voice control component 221 is also integrated above the single-layer motherboard 22, and the button voice control component 221 extends out from the top of the body 10.

[0066] Understandably, the button control component 221 enables the cleaning unit 1 to be controlled by buttons or voice. The button portion of the button control component 221 extends from the top of the unit 10, allowing the cleaning mode, travel mode, etc., of the cleaning unit 1 to be controlled by pressing the button portion. The specific structure of the button control component 221 is based on existing technology and will not be described in detail here.

[0067] Please refer again to Figures 2, 7, and 8, and also to Figures 9 and 10. Figure 9 is a front view of the cleaning unit shown in Figure 1; Figure 10 is a cross-sectional view of the cleaning unit shown in Figure 9 along line CC. In some preferred embodiments, the cleaning unit 1 further includes a traveling unit 60, which includes drive wheel assemblies 61 on the left and right sides of the robotic arm and omnidirectional wheel assemblies 62 disposed in front of the battery pack 21.

[0068] More preferably, the two drive wheel assemblies 61 are arranged opposite each other on the left and right sides of the middle position in the direction of travel of the cleaning host 1; the omnidirectional wheel is arranged in front of the battery pack 21 and below the single-layer motherboard 22, and the distance between the omnidirectional wheel assembly 62 and the two drive wheel assemblies 61 is the same.

[0069] Understandably, the drive wheel assembly 61 is configured to rotate and oscillate, thereby driving the cleaning unit 1 to move and rotate in all directions. The two drive wheel assemblies 61 are positioned relatively at the center of the cleaning unit 1's direction of travel, making the movement of the cleaning unit 1 smoother. The omnidirectional wheel assembly 62 provides support for the cleaning unit 1, increasing its stability.

[0070] In some optional embodiments, a support wheel 63 is also provided at the middle of the rear end of the cleaning unit 1. The support wheel 63 can further increase the stability of the cleaning unit 1, making it less likely to tip over during movement. The specific structure of the drive wheel assembly 61, support wheel 63 and caster wheel assembly 62 in this embodiment refers to the prior art and will not be described in detail here.

[0071] Please refer again to Figures 2 and 8. In some preferred embodiments, the rear side of the body 10 includes a charging interface 102, which is electrically connected to the battery pack 21 via a recharge circuit.

[0072] It is understood that in this embodiment, the charging interface 102 of the cleaning host 1 is located on the rear side of the cleaning host 1. The charging interface 102 can be electrically connected to an external charging power source, thereby enabling the external charging power source to charge the battery pack 21.

[0073] Please refer again to Figures 2, 7, and 8. In some preferred embodiments, the single-layer motherboard 22 is electrically connected to the recharge circuit to control the recharge circuit; in some preferred embodiments, the cleaning host 1 also includes a rear recharge board 70, which is disposed adjacent to the charging interface 102 and configured to be electrically connected to the recharge circuit to control the recharge circuit.

[0074] It is understood that this embodiment provides two control board arrangement methods for controlling the recharge circuit. In some embodiments (not shown in the figure), the control elements for controlling the recharge circuit are integrated on a single-layer motherboard 22, that is, a single-layer motherboard 22 realizes the operation control of the cleaning host 1 and the control of the recharge circuit. In other embodiments (refer to Figure 2), a rear recharge board 70 is provided at the rear end inside the cleaning host 1. The recharge circuit is controlled through the rear recharge board 70, thereby effectively dispersing the number of integrated components on the motherboard 22, reducing the area of ​​the single-layer motherboard 22, and also reducing the heat of the single-layer motherboard 22 from the source.

[0075] Please refer again to Figures 2, 7, 8, 9, and 10. In some preferred embodiments, the cleaning unit 30 includes a roller brush assembly 31, a dust box 32, a fan assembly 33, a dust outlet channel 321, and an air duct 331. The roller brush assembly 31 is located behind the robotic arm, the dust box 32 is located behind the roller brush assembly 31, the fan assembly 33 is located behind the dust box 32, and is positioned at the center of the cleaning host 1 in the left-right direction. The dust outlet channel 321 connects the dust box 32 and the dust outlet 103 on the side of the unit 10. The air duct 331 connects the fan assembly 33 and the suction port 104 on the side of the unit 10. The dust outlet channel 321, the fan assembly 33, and the air duct 331 are arranged sequentially on the rear side of the cleaning host 1.

[0076] It should be noted that the roller brush assembly 31 in this embodiment may include a roller brush and a motor 301 located above the roller brush. The motor 301 is configured to drive the roller brush to rotate. The roller brush is horizontally positioned, with a portion extending beyond the bottom surface of the cleaning unit 30's body 10 to contact the surface to be cleaned, thus brushing the surface. The structure of the roller brush is prior art and will not be described in detail here. More preferably, the rotation axis of the roller brush is parallel to the left-right direction of the cleaning unit 1 and is located at the middle position in the front-back direction of the cleaning unit 1; this arrangement ensures that the roller brush has high brushing efficiency and the cleaning unit 1 has a better cleaning effect.

[0077] The dust box 32 is located on the rear side of the roller brush. It can be understood that the dust box 32 has a first inlet on the side facing the roller brush. When the cleaning unit 1 is running, the roller brush sweeps dirt from the environment to be cleaned into the dust box 32 through the first inlet, thereby collecting the swept dirt. More preferably, two drive wheel assemblies 61 are arranged opposite each other at both ends of the roller brush, thereby driving the cleaning unit 1 to move and rotate.

[0078] It is understandable that the fan assembly 33 is configured to suck up dirt from the environment to be cleaned, and the dust box 32 has a second inlet on the side facing the fan assembly 33 for the dirt sucked up by the fan to enter. The specific structure of the fan assembly 33 is based on existing technology and will not be described in detail here.

[0079] It is understandable that the dust outlet 321 connects the dust box 32 and the dust outlet 103 on the side of the body 10, so as to empty the dirt collected in the dust box 32; the air duct 331 connects the ventilation fan assembly 33 and the dust suction port 104 on the side of the body 10, so as to allow dust in the environment to be sucked into the dust box 32 from the air duct 331 by the fan assembly 33.

[0080] Please refer again to Figures 2, 7, and 8. In some preferred embodiments, the cleaning unit 30 further includes two mopping assemblies 34. Each mopping assembly 34 includes a first drive mechanism 341 inside the body 10 and a mop 342 disposed below the body 10. The first drive mechanism 341 includes a transmission mechanism 302 and a motor 301 that provides driving force to the transmission mechanism 302. The transmission mechanism 302 is connected to the center of the mop 342 to drive the mop 342 to rotate.

[0081] The mopping assembly 34 includes a first drive mechanism 341 disposed within the body 10 and a mop 342 disposed below the body 10. The mop 342 is configured to rotate to mop and clean the bottom surface and tabletop surfaces below the cleaning host 1. The gearbox is configured to drive the mopping assembly to rotate. The motor 301 provides power to the transmission mechanism 302, thereby controlling the rotation of the mop 342. The transmission mechanism 302 is configured to drive the mop 342 below it to rotate for mopping and cleaning. The specific structures of the motor 301 and the transmission mechanism 302 are described in the prior art and will not be elaborated here.

[0082] Please refer again to Figures 2, 9, and 10. In some preferred embodiments, at least one mopping assembly 34 further includes a second drive mechanism 343 adjacent to the first drive mechanism 341 for driving the mop 342 to swing outward; wherein the second drive mechanism 343 is configured to be driven by a motor 301; or the second drive mechanism 343 includes a transmission assembly for driving the mop 342 to swing outward and a power assembly for providing driving force to the transmission assembly.

[0083] Understandably, the second drive mechanism 343 is configured to drive its corresponding mop 342 to swing outward, thereby increasing the usability of the mopping assembly 34 of the cleaning unit 30. In some embodiments, the second drive mechanism 343 is configured to share a motor 301 with the first drive mechanism 341. In other embodiments, the second drive mechanism 343 and the first drive mechanism 341 each provide two power components to drive their respective transmission components or transmission mechanisms 302.

[0084] In some embodiments, one mopping assembly 34 is provided with a second drive mechanism 343, while the other mopping assembly 34 is not provided with a second drive mechanism 343. In the specific embodiment shown in the accompanying drawings, on the rear side of the cleaning unit 1, a dust outlet 321, a first drive mechanism 341, a fan assembly 33, an air duct 331, another first drive mechanism 341, and a second drive mechanism 343 are arranged in sequence.

[0085] The present invention also provides a self-moving cleaning device, which includes the cleaning host 1 described above.

[0086] It is understood that the self-moving cleaning device provided by this invention can be, but is not limited to, a sweeping robot, a mopping robot, a sweeping and mopping robot, or other cleaning devices with cleaning functions. It is also understood that the cleaning device provided by this invention can be used not only for cleaning floors, but also for cleaning desktops and other platforms or non-platforms. The above are examples of application scenarios for the self-moving cleaning device provided by this invention and should not be construed as limiting the application scenarios of the self-moving cleaning device provided by this invention.

[0087] The self-propelled cleaning device includes the aforementioned cleaning host 1. It is understood that the cleaning host 1 is designed to move within the environment to be cleaned and to clean that environment. The cleaning host 1 includes a robotic arm, enabling it to grasp or move objects such as obstacles or debris. The robotic arm is designed to fold and store within the storage compartment 40 of the body 10, ensuring a high degree of integration for the cleaning host 1. The single-layer motherboard 22 of the control unit 20 of the cleaning host 1 extends into the storage compartment 40 inside the body 10 of the cleaning host 1. When the robotic arm is extended, it does not contact the single-layer motherboard 22, resulting in a reasonable arrangement of components within the body 10 of the cleaning host 1. This avoids the technical problem of increased height and low integration caused by stacked double-layer motherboards 22.

[0088] In some embodiments, the self-propelled cleaning device further includes a cleaning base station, which is configured to clean the cleaning unit 30 of the cleaning host 1. Cleaning includes, but is not limited to, collecting debris from the dustbin 32, washing the rag 342, and removing dirt entangled on the roller brush assembly 31. Preferably, the cleaning base station has tracks corresponding to the two drive wheel assemblies 61 of the cleaning host 1, allowing the cleaning host 1 to drive into them. When the cleaning base station is in operation, the cleaning host 1 drives into the cleaning base station, and the cleaning base station cleans the cleaning unit 30 of the cleaning host 1.
